Hiberfil

I have in drive C: a large file named hiberfil.sys (about 1Gb).I thought at first it is a file constituted when I made my computer hibernate.But I did not hibernate my computer for a certain time now and the hiberfil.sys file is quite recent.Moreover, I booted on another disc, deleted the hiberfil.sys file on the old disc, but when I reboot on the old disc again it returns!Could anyone tell me what file the hiberfil is and if I can and how get rid of it? It takes my precious disc realt estate.Thank you

Hi, the hiberfil.sys file is a file that is created when Hibernation is enabled on the system. It saves system configuration and settings for a faster power up coming out of hibernation when you hit the spacebar or shake the mouse. Sometimes this file can get rather huge as you've no doubt discovered.

The fix: (You must be logged on as an Administrator)

Go to Start > Control Panel > Performance and Maintenance > Power Options > Hibernate tab, de-select the "Enable hibernation" check box, click OK. Close the Control Panel and reboot, the file will disappear.

Put the check back in the box if you wish to re-enable Hibernation in the future.
